99456 Medicaid reimbursement rate by state (2026)

• Order. States are listed from the highest published rate to the lowest. No single unit is shared by 8 or more states for 99456, so the order is by published amount and is not a like-for-like rank.
• Medicaid rate. The most the state's fee-for-service program pays for one unit, as published. 3 of the 7 states list more than one rate for 99456, by modifier, provider type or setting; the table shows the one that matches the provider level and setting used across states, without add-ons.
• Unit. Of the 7 states, 1 publish 99456 per session, and 6 schedules print no unit at all (a flat amount per service).
• Per hour. 99456 is not billed in time units in these states, so no hourly figure is shown.
• Managed-care plans. The rule the state sets for its plans on this rate. What each rule means is explained below.
• % of Medicare. No Medicare physician fee schedule amount is on file for 99456, so there is no percentage.
• Source and date. Each Source link opens the state's own document; “since” is the date the rate took effect.

Published rates for 99456 run from $50.00 in Kansas to $2,500.00 in Minnesota, a 50.0x gap in the same unit. Half the states pay more than the median of $152.54 and half pay less. The usual reasons for a spread like this in physician & professional rates:

• Modifiers such as professional or technical component, bilateral, multiple procedure and assistant at surgery change the amount paid, and states apply them with their own percentages.
• Each state sets its own physician conversion factor or fee for every code, and many update them on a state budget cycle rather than on Medicare's calendar.
• Many schedules pay differently by place of service (office versus facility) and by practitioner, and nurse practitioners and physician assistants are often paid a percentage of the physician amount.

Timing matters too. 1 state set the current rate for 99456 in 2026 or later, while 4 states still pay a rate that took effect in 2022 or earlier. A state that has not updated its rate in years will drift down the ranking as others raise theirs.

Most Medicaid members are in managed-care plans, and plans don't publish their provider fee schedules. For 99456, the public signal is the rule each state sets for its plans, recorded on each rate above.

In 3 states, plans negotiate and the published rate is a benchmark or out-of-network default. In 1 state, the service is paid outside the plans or through a state-directed payment. The rule for the remaining 3 states is not classified yet.

• Plans negotiate; the published rate applies out of network (3 states). In-network rates can be above or below the published rate. The published rate is the benchmark both sides know, and the fallback if no contract is signed.
• Paid by the state, outside the plans (1 state). Bill the state's Medicaid program, not the plan, at the published rate. There is no plan contract to negotiate for this service.

Plan-negotiated rates are never estimated here. To see the rule and its citation for a particular state, open that state's managed-care page, for example Minnesota managed care.

99456 is a CPT evaluation and management code in the physician & professional line, billed mostly by physicians, nurse practitioners, physician assistants and other licensed practitioners. Evaluation and management codes are billed once per visit. The code itself sets the level of the visit, so there is no time unit to multiply, and the setting (office, hospital, facility) decides which code applies.

Practitioners who are not physicians are often paid a reduced percentage of the published amount, so check the schedule for the reduction that applies to your provider type. Physician-fee-schedule codes are billed per service: one unit is one occurrence unless the code itself is defined by time or quantity.

Before billing, confirm the rate, unit and any modifier with the state's current schedule or the plan: the amounts here are as published, not a guarantee of payment.
